A cross-sectional study on coronary artery disease diagnosis in patients with peripheral artery disease

Purpose: Compared with healthy individuals, patients with peripheral artery disease(PAD) generally have a very high risk of subclinical Coronary artery disease(CAD) and cardiovascular events. To determine the correlation between CAD in PAD patients, thereby promoting the lifetime of PAD patients and reducing the serious impacts of CAD.Methods: This clinical-based cross-sectional study comprised 100 consecutive patients in India from 2014 to 2016.In this research, PAD patients were screened for CAD by treadmill stress test and cardiac colour Doppler examination. In addition, this study performed coronary angiography followed by peripheral angiography for patients who could not perform the treadmill test.Results: With the statistical results, the study observed a high prevalence of CAD in PAD patients that can be detected only with angiography. Further, 30.93% of asymptomatic CAD prevalence was observed in PAD patients.The study strengthens the need for coronary angiography in all symptomatic lower limb PAD cases to detect early CAD, particularly in patients with diabetes and dyslipidemia.Conclusion: There exists a strong correlation between PAD and CAD. Hence, precise diagnosis followed by supervision of PAD patients is significant for avoiding local progression of cardiovascular risk.
